TMZ followed up on its initial report Monday afternoon with news that his parents also were in attendance, which would make any alcohol consumption legal under Texas law—though the report also cites the owner as saying no one saw Manziel drinking.

Manziel spoke to the media Sunday about his Friday night at the Avenu Lounge in Dallas, saying he did nothing wrong or illegal.

"It's tough knowing that everything you do is watched pretty closely because I'm doing the same stuff I've always done," Manziel said, per USA Today. "It's just now people actually care what I do."

"It's hard to watch some of the stuff that people say to you when you take a picture or you do some stuff or you're at these games or whatever. It's tough to sit back, and you can't really defend yourself regardless of how much you want to scream out, 'I've been doing this forever. This is nothing new for me.' "

Manziel has been on the defensive for a variety of off-the-field events since his on-the-field rise as "Johnny Football." His NBA courtside seats drew questions in December, and he was called out earlier in the week after posting a picture holding money at a casino. To the latter, Manziel lashed out on Twitter, saying, "Nothing illegal about being 18+ in a casino and winning money...KEEP HATING!"

The picture later was deleted, but as is the case with social media, the damage already was done.

Manziel led Texas A&M to 41-13 win over Oklahoma on Friday, accounting for 516 yards of total offense and four touchdowns. He has three more year of collegiate eligibility remaining.
